First solve the length of side BC, CD, EF and FA
Since BC = CD = sqrt( 10^2 + 10^2)
BC = CD = 14.1421
FA = EF = sqrt(10^2 + 20^2)
= 23.3607
So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607
= 93
The area is made up be triangle FAE, rectangle ABDE and
triangle BCD
A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)
<span>A = 500 sq units</span>
Answer:
Step-by-step explanation:
x²+x²=14²
2x²=196
x²=196/2=98
x=7√2 ft
Answer:
Step-by-step explanation:
Δ =
VΔ = 4 * 8 = 32
a = (- 4 ± 32) *
a' = 7/2
a''= 9/2
T + 49 This is the answer because by saying “more than” you are adding and the symbol for adding is “+”.
Answer:
78
Step-by-step explanation:
Write out the 13 times tables: 13, 26, 39, 52, 65, 78, ... 78 is the 6th number.
You can also do 13 × 6 which is 78.
Hope this helps!
